10-Minute Learn Procedure

CAUTION: When replacing either the Passkey® III (PK3) keys, ECM or theft deterrent control module and the 10-minute relearn procedure is used, ensure that the appropriate calibration is selected for the replacement component on the calibration selection screen of the service programming system. The appropriate calibrations for specific VTD system components are described below:
  • When replacing PK3 keys and the 10-minute relearn procedure is used, the Vehicle Theft Deterrent Learn for Passkey III System Control Module calibration is required. This clears all previously learned keys from the theft deterrent control module and enables the theft deterrent control module to learn new PK3 keys.
  • When replacing an ECM that has previously learned another vehicles theft deterrent control modules fuel continue password and the 10-minute relearn procedure is used, the Vehicle Theft Deterrent Learn for Powertrain System Control Module calibration is required. This clears the previously learned fuel continue password in the ECM and enables the ECM to learn the next fuel continue password it receives.
  • When replacing a theft deterrent control module and the 10-minute relearn procedure is used, the Vehicle Theft Deterrent Learn for Powertrain System Control Module calibration is required. This clears the previously learned fuel continue password in the ECM and enables the ECM to learn the next fuel continue password it receives.
NOTE: This procedure requires a Tech 2® scan tool and a Techline® terminal with current SPS (Service Programming System) software.
NOTE: Use this procedure after replacing the Passkey® III (PK3) keys, theft deterrent control module or ECM.
NOTE: If replacing a theft deterrent control module with a GM SPO replacement part, perform the procedure to setup a new theft deterrent control module prior to the 10-minute relearn procedure. See SET UP A NEW THEFT DETERRENT CONTROL MODULE .
  1. Connect scan tool to vehicle.
  2. Turn ignition on, with engine off.
  3. Ensure that all power consuming devices are turned OFF on vehicle.
  4. With scan tool, select Request Info. under Service Programming System and follow scan tool on-screen instructions.
  5. Disconnect scan tool from vehicle and connect scan tool to a Techline® terminal with the current Service Programming System (SPS) software.
  6. On the Techline terminal, select Service Programming System and follow Techline terminal on-screen instructions.
  7. Disconnect scan tool from Techline® terminal and reconnect scan tool to vehicle.
  8. With a master Passkey® III key, turn ON the ignition, with engine OFF.
  9. With scan tool, select Program ECU under Service Programming System.
  10. At this point the scan tool must remain connected for the duration of the 10-minute relearn procedure.
    11. NOTE:
    • The scan tool will initially display 12 minutes. The first 2 minutes allow the scan tool to initialize the appropriate control module. The remaining 10 minutes is the relearn timer.
    • On some vehicles, the SECURITY telltale maybe illuminated on steady for the duration of the 10-minute relearn procedure.
  11. Observe scan tool, after about 10 minutes, scan tool will display "Programming Successful, Turn OFF Ignition". The vehicle is now ready to relearn the key information and/or the passwords on the next ignition switch transition from OFF to CRANK.
  12. Turn OFF ignition and wait 5 seconds.
  13. With master Passkey® III key, start engine. The theft deterrent control module has now learned the key transponder information and ECM has now learned the fuel continue password.
    14. NOTE: Perform this step ONLY on vehicles with EXPORT configured theft deterrent control modules.
  14. Turn OFF the ignition and wait 15 seconds minimum.
    15. NOTE: Perform this step ONLY on vehicles with EXPORT configured theft deterrent control modules.
  15. With a second master Passkey® III key, start engine. The theft deterrent control module has now learned the second master Passkey® III key transponder information.
    16. NOTE: If more than one valet key is to be learned, immediately precede each valet key with a learned master key.
  16. If additional keys are required to be learned, using a previously learned master key, turn ON the ignition, with the engine OFF. Turn OFF the ignition and remove the key. Within 10 seconds insert the key to be learned. Turn ON the ignition with the engine OFF. The vehicle has now learned the new key.
  17. Using scan tool, clear any DTCs.
